Concentrating solar photovoltaics
There's another type of solar power that's vying for market share called concentrating photovoltaics. This plant is being constructed in the San Luis Valley in Colorado where these large collectors use mirrors to concentrate sunlight onto very efficient solar cells. Concentrating the light boosts the output but these systems require trackers and can be more complex than regular flat panels.
